Answer:

AlS2O6

Explanation:

Elements                                       Al                    S                 O

Mass percent                             15.80                28              56.2

Molar Mass                                   27                   32               16

Mass percent / Molar mass       0.585             0.875            3.5125

                                                        /                       /                    /

Smallest ratio                              0.585             0.585           0.585

      ≈                                                  1                      2                   6

From the table above Al has 1 , S has 2 , and O has 6, Therefore;

AlS2O6
